Abstract:
Objective:To investigate the correlation between the types of unicate process (UP) superior attachment and the chronic frontal sinusitis without nasal polyps(CFSsNP).Method:The images of 240 sides of frontal recess were evaluated. The types of UP superior attachment was compared between the CFSsNP group and the control group. The correlation between UP the superior attachment and CFSsNP were analyzed. Result:Seven types of UP superior attachment were identified. The most common type in the two study groups was type 1(insertion into the lamina papyracea). The occurrence rate of type 1 of UP superior attachment in the CFSsNP group was significantly higher than that in the control group(59.8% and 36.4%,respectively P<0.01),but type 5(insertion into both the lamina papyracea and the skull base) was significantly less frequent in the CFSsNP group than in the control group(9.8%,28.8%,P<0.01). Logistic regression analysis revealed that the type 1 of UP superior attachment was an independent risk factor for CFSsNP(OR=1.181,P<0.05),and that type 5 of UP superior attachment was a protective factor for CFSsNP(OR=0.391,P<0.05). Conclusion:UP superior attachment varied significantly,with the most common type being type 1; This type is intimately related to CFSsNP.

Correlation
Two variables, for example, a and b, are said to be positively correlated if both variables move in the same direction. In other words, a positive correlation exists between two variables, a and b, if:
